Abstract
In the case where processing is implemented in a medium mode, by interconnecting connectors 10 and 28, processing of information to be displayed on a memory type display panel 2 is implemented by a host display processing device 21; in the case where processing is implemented in a stand-alone mode, by disconnecting the connectors 10 and 28 from each other, processing of information to be displayed on the memory type display panel 2 is implemented by an information display sheet 1 itself.
Claims19
An information display comprising:
- a displaying device which displays information;
- a low-speed CPU configured to control an entirety of the information display, reads out and implements programs, and includes an autonomous processing section and a heteronomous processing section;
- a data memory configured from a nonvolatile memory and stores document data;
- a display driver which displays document data stored in the data memory, and information processing results inputted by the low-speed CPU on the displaying device;
- and
- a connector which detachably and attachably connects the information display having the autonomous processing section and the heteronomous processing section to an outer device outside of the information display and which transfers a processing request to the outer device to heteronomously implement processing of information,
- the autonomous processing section autonomously processing the information to be displayed on the displaying device and the heteronomous processing section causing the outer device to process the information to be displayed on the displaying device based on a load on processing of the information to be displayed on the displaying device.
4 more elements
An information display system comprising:
- an information display sheet which displays information processed autonomously within the information display sheet;
- a host display processing device which processes information to be displayed on the information display sheet;
- and
- a connector which detachably and attachably connects the information display sheet to the host display processing device,
- wherein the information display sheet includes:
- a low-speed CPU which is adapted to control an entirety of the information display sheet, reads out and implements programs, and requests the host display processing device to process an issued processing request when the issued processing request cannot be autonomously processed by the information display sheet based on a load on processing of the information processed autonomously within the information display sheet,
- a data memory in the information display sheet and which is configured from a nonvolatile memory and stores document data, and
- a display driver in the information display sheet and which displays document data stored in the data memory, and information processing results inputted by the low-speed CPU on the information display sheet.
5 more elements
An information display, comprising:
- a displaying device which displays information;
- a low-speed CPU which is adapted to control an entirety of the information display, reads out and implements programs, and includes a controller configured to autonomously process the information to be displayed on the displaying device;
- a data memory which is configured from a nonvolatile memory and stores document data,
- a display driver which displays document data stored in the data memory, and information processing results inputted by the low-speed CPU on the displaying device;
- and
- a connector which detachably and attachably connects the information display to an outer device outside of the information display, and transfers a processing request to the outer device to heteronomously implement the processing of the information by the outer device,
- wherein the controller causes the outer device to process the information to be displayed on the displaying device based on a load on processing of the information to be displayed on the displaying device.
